The difference between those two wires will be the thickness. The 10/2 is thicker which is good up to 250ft and 12/2 is good up to 150ft. Both could work if you are in the within those lengths. We do not offer any Bluetooth modules or know if they are compatible with our units.

While the length of runs could have worked with 12/2, this wire was ordered to allow future expansion - which has already happened. Flexibility was superior to other vendor's lighter gauge stranded wire and this wire stripped without a fight.

I am very pleased with my all my Volt products including pathlights, spots, led bulbs and wire. One issue I've had is with the hammerstakes. The pathlights are difficult to screw into the threads making the light crooked. I've since ordrerd the stakes with the brass insert. Much better but still had a couple of threading problems. Neighboors have complimented the look of the lighting.
